Soil organic carbon (SOC) is closely tied to soil health. However, additional biological indicators may also provide insight about C dynamics and microbial activity. We used SOC the other (potential mineralization, permanganate oxidizable C, water extractable β-glucosidase enzyme activity) from North American Project Evaluate Health Measurements examine continental-scale drivers of these indicators, relationships among effects health practices on indicator values. All had greater values at...
Aggregate stability is a commonly used indicator of soil health because improvements in aggregate are related to reduced erodibility and improved soil–water dynamics. During the past 80 90 years, numerous methods have been developed assess stability. Limited comparisons among resulted varied magnitudes response management practices influences inherent properties climate. It not clear whether selection specific method creates any advantage investigator. This study assessed four measuring...
Abstract Currently accepted pedotransfer functions show negligible effect of management‐induced changes to soil organic carbon (SOC) on plant available water holding capacity (θ AWHC ), while some studies the ability substantially increase θ through management. The Soil Health Institute's North America Project Evaluate Measurements measured content at field using intact cores across 124 long‐term research sites that contained increases in SOC as a result management treatments such reduced...
Abstract Farmers, scientists, and other soil health stakeholders require interpretable indicators of hydraulic function. Determining which to use has been difficult because measurement disconformity, spatial temporal variability, recently established treatments, the effect site characteristics on management practice differences. The North American Project Evaluate Soil Health Measurements includes 124 sites uniformly sampled across a range practices in America 2019. We compare recommend...
Abstract Various soil health indicators that measure a chemically defined fraction of nitrogen (N) or process related to N cycling have been proposed quantify the potential supply crops, key function. We evaluated five (total N, autoclavable citrate extractable water‐extractable organic potentially mineralizable and ‐acetyl‐β‐ D ‐glucosaminidase activity) at 124 sites with long‐term experiments across North America evaluating variety managements. found 59%–81% variation in was among sites,...
Potential carbon mineralization (Cmin) is a commonly used indicator of soil health, with greater Cmin values interpreted as healthier soil. While are typically in agricultural soils managed minimal physical disturbance, the mechanisms driving increases remain poorly understood. This study assessed bacterial and archaeal community structure potential microbial drivers maintained under various degrees disturbance. mineralization, 16S rRNA sequences, characterization data were collected part...
En México la demanda de grano maíz para consumo humano y pecuario es alrededor 38 millones toneladas; sin embargo, solo se producen entre 25 28 millones, el resto importa Estados Unidos. El déficit en producción debe principalmente al uso variedades no apropiadas, manejo deficiente del cultivo a problemas bióticos abióticos que ocurren regularmente durante ciclo cultivo. Ante necesidad contar con híbridos más productivos, Instituto Nacional Investigaciones Forestales, Agrícolas Pecuarias...
Highlights• Four common indicators of aggregate stability were assessed across North America• Aggregate moderately correlated with each other• All influenced by inherent soil properties and climate• Indicators sensitive to tillage, cover crops, organic amendments, residue• Indicator responses tillage other health
